INTERNAL COMBUSTION ENGINE Filed Nov. 17, 1936 5 Sheets-Sheet 5 INVENTOR FREDERICK W; Jones ATTORNEYS 35 In the accompanying Patented Apr. 11, 1939 UNIT D STATES PATENT OFFICE This'invention pertains to internal combustion engines, and more particularly to a rotary engine in which the operative steps of expansion, intake, exhaust and compression occur during 6 two revolutions of the rotor.

The invention has primarily for its object to produce an exceedingly simple and emcient engine of the foregoing type, utilizing a rotary piston mounted on the crank shaft, and control 10 valves operably connected with the crank shaft to effect the operative cycles, namely, expansion, intake, exhaust, and compression, through two revolutions of the rotor or piston.

Incidental to the foregoing; a more specific object of the invention resides in the provision of an engine having the foregoing characteristics,

and provided with a plurality of abutments automatically actuated by the rotor in effecting the operative cycles. V

l A more specific object resides in the provision of rotary valves operativelyconnected with the crank shaft of the engine through suitable gearing for controlling not only the cycles, of operation, but also designed to relieve ineflectual pres- 'sure upon the rotor.

With the above and other objects in view, which wi1l:.appear-'as the description proceeds, the invention resides in he novel construction, combination, and arrangement of parts, substan- 30 tially as hereinafter described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims. drawings is illustrated "one complete example of the physical embodiment of the present invention constructed acpractical application of the principles thereof.

Referring now. more particularly to the accompanying drawings, which, for the purpose of simplicity, illustrate a single cylinder, it will be appreciated'that the invention is applicable to any number of cylinders disposed side by side,

j and provided with a common crank shaft, as indicated. in Figure 2. Furthermore, while the cording to the best mode so far devised for the of the invention.

with particular reference to Figures 1 and 2, the numeral l designates a block provided with a a transverse annular compartment 2, which functions similarly to the cylinder in a conventional reciprocative type engine. The block is also provided with a water jacket 3, through which water may be circulated in the usual manner, to

effect cooling of the block. While any mounting for the block may be employed, in the present engine it is proposed to fasten the same to a pair of laterally extending brackets 4 (shown in dot and dash lines in Figure 2), which may be u The block I is ing bosses 5 opposed to each and I 2. respectively.

the valves 21 and 35 are geared for one revolution to two of the crank shaft, and through the one-to-one gear ratio between the valves and 31 these valves will rotate in synchronism.
